The extraction procedure of home-address numbers can usually be implemented by the character recognition techniques. However, it is difficult for many character recognition methods to distinguish distorted or noise-overlapped home-address numbers precisely. To cope with this difficulty, we address a complementation method to infer undeterminate home-address numbers, using already established home-address numbers of neighboring house blocks. Our method first estimates the address difference among home-address numbers on the basis of house block layout pattern, and then infers the undeterminate home-address number from adjacently surrounded house blocks. We also evaluate our method through experiments.}, pages = {1245--1254}, title = {Estimation of home-address numbers on the basis of relationships and directions among house blocks}, year = {2001} }
